Loss of Data and Incorrect Billing

I have a query with Vodacom since 26 August 2017 (Ref: 1- ********** ********** ) about the loss of data. It's been an issue with Vodacom for a over a week where their clients Data just disappears and then they get billed for Data they didn't even used. It's been more then 48 Hours and still haven't heard anything from them. When I phoned yesterday the Customer Service Consultant told me that my Query haven't been allocated to the correct person as of yet and that he will sort it out for me and call me back at 12:00 today. Still I've heard nothing and yet Vodacom have billed me for Data that I haven't used.
